sPECIFICATION forming part of Letters Patent N0. 630,304, dated August1, 1899. Application filed March 20,1899. Serial 110.709.726. (Nomodel.)

To aZZ whom it may concern:

Be it known that 1, FRANKLIN SCHNEIDER, a citizen of the United States,residing at Cleveland, in-thecounty of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Car-Trucks and I 'dodeclare that the following is a full, clear,'and exact description ofthe invention, which will enable others skilled in the art to whichit'ap.

pertains to make and use the same.

My invention relates to improvements in car-trucks; and the inventionconsists in the construction, combination, and arrangement of the parts,substantially as shown and described, and particularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is an elevation of a portion of acar-truck containing a full embodiment of my invention in connectionwith one of the car-axles and the springs associated therewith, ashereinafter fully described. Fig. 2 is a plan View looking down onsection-line 2 2, Fig. 1, but omitting the elliptic spring. Fig. .3 is asectional elevation on line 3 3, Fig. 1, at the right of the figure.Fig. 4 is a cross-sectional elevation looking to the right on line 4 4,Fig. 1. Fig. 5 is aplain elevation of one section or side of thepedestal, and as both sides are alike this view will suffice toillustrate this part of the invention. Fig. 6 is a plan view of Fig. 5,showing some of the structural features within the sides of eachpedestal-section. Fig. '7 is a modification of the spring over thejournal-box. Fig. 8 is a detail.- in side elevation of one of thedetachable stir.- rups for supporting the coiled springs onthe pedestal.Fig. 91s a detail of the spring posts or rods.

The parts constituting the invention are assembled and in workingrelation in Fig. 1, where, however, onlyhalf of a complete truck isshown, this being sufficient to disclose and understand the invention.

A represents the side bars of the truck, there being two on each side ofthe car, as usual, and constituting practically a single part of thetruck when'united, between which the pedestals and other parts arearranged, and the said bars are locked together, as will hereinafterappear.

13 are the pedestals or sections of pedestals ,if the, two togethenbeconstruedas one,

there being two associated in'all cases and exactly alike, so that theillustration and description of one is sufficientfor all. Thesepedestals or sections of pedestals are constructed to occupy the fullspace between side bars A and completely fill said space, so that noblocks or other means of any kind are necessary to space said bars or toafford means through which the side bars may be bolted. The form oroutline of the pedestals is clearly seen in Figs. v5 and 6, wherein aplain elevation discloses a structure substantially L- shaped, inverted,with the long straight outer edge of the stem of the L exposed tothejournal-box 0, while the other or right-angled portion and presumablythe shorter side of the L lies wholly between the bars A'an'd a recessoccurs in the otherwise unoccupied portion of the pedestal, as willhereinafter appear. The special features of the pedestal thus outlinedand arranged are, first, the several integral spacing-sleeves 2, throughwhich pass heavy bolts 3 for rigidly and firmly locking the bars A andthe pedestals togetheia. Other features of the pedestal are the internalbosses or eyes 4 near its middle, but below the side barsA, the integralsolid part.5,having a cen- -tral vertical bearing or passage a for theupper and heavier portion of the spring bolt or post, and the two setsof lugs 6 and 7 on the outer corners of its recess. Thede'pending'portion of the pedestal sustains the same cross-section as the upperbolted-in part and is construced of flangedopen-work, so as to have therequisite strength and yet be relatively light in weight. Now assumingthat two companion pedestals or sections of a pedastal thus fashionedare assembled and bolted onto the frame, as in Fig. 1, the journal-box Gis located between them and sustained both laterally and axially, asusual-that is, the pedestal has no new relation to or with the journal-box as such. To the top of the journal-box is seated the ellipticspring D, and the ends of this spring are supported each by a pair oflinks d, pivoted at their lower ends on a bolt 61, which passes throughthe bosses or eyes 4 of the pedestal, and said links are connected attheir upper ends by bolts or rods d engaged this advantage, amongothers, that by simply removing the bolts d, which are convenientlyexposed at their ends, the spring D is wholly separated from thepedestalB and frame A and can be removed.

E are the spiral springs, arranged in pairs in connection with thepedestals B and seated each on an L-shaped bracket Fin the recess in theouter edge or portion of the pedestal B. This bracket is formed withopenings through its ends for the passage of securingbolts 0 c, thelatter being shown also in Fig. 2, where the lower end of the bracket isseen as coming between the sides of the pedestal lugs or ears 7, as itdoes between lugs 6 above, or it might have overlapping portions atthese connections, it thought best. The spring E is seated directly uponthis bracket, and the rod or post G connects the sill-plate of thecar-body with the truss-bar J below through the passage in the solidpart 5 of the pedestal, the spring E, and the lower part of bracket F,which carries said spring. At its bottom 1 a suitable nut is threadedonto the rodv G, and at its top a cap 9 is aifixed to the sill-plate H,having a socket adapted to receive the end of the said rod, and atransverse pin it fastens the rod therein. This construction andarrangement of these parts affords the utmost convenience when occasionarises to separate the parts to mend a break from accident or otherwise.Suppose, for example, that in an accident the rod G should become bentor the spring E injured so as to demand repair. By removing the twoconvenient bolts 0 and c and the pin h both spring and rod would beavailable, and, as already pointed out, the removal of bolts (1liberates spring D, and all this can be done in a few moments withpractically no other tool than a suitable wrench.

Yet when the parts are connected up they are every way most serviceableand durable. It should be noted also that rod or post G has twodiameters, the upper one being largest and affording a shoulder g forthe springbearing cap L and through which the weight from above rests onsaid spring. Ordinarily there is no danger of noise at this point; but

placed between cap g and the metallic surface above. A bar or strap 12connects the pedestals beneath the journal-box 0.

Another part of the invention is seen at the right in Fig. 1, Where itwill be observed that the single elliptic spring M is supported betweenthe bars A. It is desirable for several important reasons to make thebars A straight or without a dip or downward bend at their ends, as hasbeen common, and I am enabled to preserve this construction andadvantageand support the spring itself in a novel and advantageousmanner by employing a dropbracket N, which hangs suspended from the barsA, to which it is riveted or bolted, and supports the spring Mfrom itscenter. This carries the spring between the bars A and, as shown here,with its top practically flush with the top of said bars, so that thespring is in the best place possible for sightliness and protection andhas its bearing brought down to an advantageously low position.

In Fig. 7 I showa modification of the spring mechanism over thejournal-box, there being here a spiral spring R instead of the semielliptic in the other views and a' bridge-piece S between the twoadjacent connectingsleeves of the two pedestals, against which thespring bears at its top, while it rests on the journal-box below in thesame manner and to the same end as the other form of spring.

What I claim as new, and desire to secure by Letters Patent, is

1. In car-trucks, the pedestal substantially as described havinga recessi'nits outeredge, a right-angled bracket for said recess and secured atits ends to the pedestal, a spring resting on said bracket in saidrecess and a post extending through the bracket, spring, and pedestal,substantially as described.

2. The side bars and the pedestals therein, and substantially L-shapedspring-supportin g brackets fixed rem ovably to the pedestals at theirends, a spring on each pedestal and a post for each spring having itsbearing in the pedestal above, in combination with the journal-boxes, aspring supported on each box and a set of links supporting the ends ofthe spring on the pedestal, substantially as described.

3. In car-trucks, a pedestal substantially as shown and described,thesame being substantially L-shaped and having a straight upper portion tobe bolted between the side bars and formed with spacing-sleeves 2 forthe bolts, a. solid portion 5 for the bearing of the spring-post, andprojections 6 and 7 for securing the spring-carrying bracket,substantially as described.

4. In car-trucks, a pedestal constructed to occupy the full spacebetween the side bars of the truck-frame and to be bolted therein andhavinga recess in its outer edge,and asubi stantially L-shapedspring-carrying bracket if there be a washer or block of some suitablematerial to deaden the noise may be bordering said recess at one sideand bottom, and detachably fixed to the pedestal, substantially asdescribed.

5. The side bars and the pedestals bolted between the same, and havingeach a central vertical bearing between said bars for the spring-postand a recess in its outer side he neath said bearing and bars, incombination with an angular bracket in said recess and fixed to saidpedestal at its ends, a coiled spring resting on said bracket and a postthrough said spring and the said bearing in the bracket, substantiallyas described.

IIO

6. The truck having side bars, a pair of pedestals between the said barsand a journal-box between the pedestals, in combination with a springconnected with the pedestals at its ends and resting at its middle onthe journal-box, a separate substantially L- shaped bracket supported onthe outside of each pedestal, a coiled spring on each bracket and a postextending through each of said springs and brackets and through theupper portion of the pedestal, substantially as described.

7. The truck having a pair of side bars and a pair of pedestalsremovably bolted between said bars, in combination with the journalboxbetween said pedestals, a leaf-spring seated on said box and inclinedlinks pivoted on said pedestals and engaging the ends of directly ontothe pedestals, substantially as 26 described.

8. The side bars of the truck, a substantially U-shaped bracket attachedat its ends to the ends and lower edges of said bars, and a fullelliptic spring seated between the sides of said bracket beneath theplane of said bars and arranged to operate between the bars, the spaceabove said bracket between the ends of said bars being open and free forthe spring-supporting bracket on the car body to play between said bars,substantially as described.

Witness my hand to the foregoing specification this 11th day of March,1899.
